We often count on how reliable our iPhones are – so much so that many of us panic in the very rare case that our device freezes due to a bad app or an incorrect update. Because of this, it's a handy skill to know the basics of debugging, and this still applies to the iPhone X S X S Max, and iPhone X R . Force restart is usually the first tactic to use.

In some ways, the knowledge of how to perform a force restart can be transferred to Apple's latest flagships, as they use the advanced but not yet proven A1

2 processor based on 7nm architecture. As stable as iOS is, we still recommend covering all your bases, just in case your iPhone X S X S Max or X R experiences hardware- or software-related hiccups.

If you have one of these new devices, it may even be difficult to shut down the device, unless you come directly from the iPhone X, where the same process exists. To shut down, you must either open your iPhone's app settings and press the Shut Down button, or press the side button and the volume up or down buttons at the same time.

The power-off key combination is much like you would forcibly restart older iPhone models, just as you reboot the iPhone hard X S X S Max, or X R ? Well, it's the same process as on the iPhone X.

Quickly press the volume button and release it, then do the same for the volume button. Then hold down the side button for about 10 seconds or until the display turns off abruptly. Hold down the side key and release it only when your iPhone returns to the Apple home screen. In list form, this is:

Press the volume key

Press the volume key

Press and hold the side key for about 10 seconds.

Release the side button when you see the Apple Home screen

After you successfully perform a hard reboot, your iPhone will start up normally and get all your valuable information. You can continue to investigate the device from there and trace your steps to check if your device is malfunctioning, be it a problematic app or a malfunction in iOS itself that might require an update or software restore via iTunes. t Miss: 100+ coolest new iOS 12 features you need to know
